Closes #562.

shell: true was added to fix python3 issues a while back #391 we should make sure we aren't making that worse

I can't seem to repro #562 on my machine - I get the expected output?

shell: true is necessary otherwise you have to explicitly put .bat extensions to run them. Testing on this branch, I actually can't run e d gn --help with these changes:

Running "gn --help"
ERROR Failed to run command:
 Error: spawnSync gn ENOENT

@codebytere, can you provide more environment details that might shine some light on the issue? I'm testing on Windows 10, Node.js 16/18/20 and don't see it.

@dsanders11 sorry i abandoned this but: I was running git bash in Windows 11.
